Consider the following time series data. Week 1 2 4 5 6 Value 18 14 16 12 17 14 a. Construct a time series plot. 1 Time Series Value 20 -10 2 5 Week 2 Time Series Value 20 -10 5 Week Time Series Vale 20 F10 Wook Select your answer What type of pattern exists in the data? Select your answer. b. Develop the three-week moving average forecasts for this time series. Compute MSE and a forecast for week 7 (to 2 decimals if necessary). MSE The forecast for week 7 c. Use a = 0.2 to compute the exponential smoothing forecasts for the time series. Compute MSE and a forecast for week 7 (to 2 decimals) MSE The forecast for week 7 a. compare the three-week moving average approach with the exponential smoothing approach using a 0-2 which appears to provide more accurate forecasts based on MSE? Explain. The three-week moving average provides a - Select your answer forecast than the exponential smoothing approach since it has Select your answer MSE e. Use smoothing constant of a = 0.4 to compute the exponential smoothing forecasts. Compute MSE (to 2 decimals). Does a smoothing constant of 0.3 or 0.4 appear to provide more accurate forecasts based on MSE? Explain The exponential smoothing forecast using 0.4 provides a select your answer forecast than the exponential smoothing forecast using a 0.2 since it has a Select your answer. MSE
